In a report from Famitsu, a new storyline that involves Tyrant Valvatorez and Sister Artina will be added. No further info as to what it will be about but Disgaea fans can expect it when the game releases on the PS Vita several months from now. In addition to the new storyline, don’t forget that the game will also have all DLC released from the PS3 version, just like Disgaea 3 on the PS Vita.
Currently, Disgaea 4 Return will be available in Japan early next year. No word yet from NIS America if they will bring the game but it’s very likely that they will.
